Orbeon- Setting up a DBService

I have read all the Orbeon documentation I can find and I am still stuck on the DB access stuff.

1. I have created a field using the “Text Output” wiget. 开发者_如何转开发And gave it the name of DBData.
2. I then created a DBservice called orbeon_data_load using the JNDI “orbeondb” as defined in our configuration.
3. Finally I created an action called “DataFromDB” , that on the "form-load" event, should populate the “Text Output” widget I named DBData.
4. I’m not sure how to debug this.

In this case, the issue was caused by an incorrect JNDI name.
